To get the works that an person has written It would use SPARQL with
something link "SELECT * WHERE { ?work wdt:P50 ?author }".
I could also get the authors of a work via Wikidata MediaWiki API.
My question is whether it is possible to get the works of an author
given the author. With my knowledge of the API, I would say it is not
possible, except if you do something "Special:WhatLinksHere"
(list=backlinks) and process/filter all the results.
